Im trying to downgrade my SPL from 4.50 to 3.XX.
Here are my phone details:

Model: HTC HD7 T9295
Carrier: AT&T
Software: Windows phone 7.5
OS version: 7.10.7720.68
Firmware revision number: 2250.21.40505.502
Hardware revision number: 0002
Radio software version: 5.69.09.29a_22.50.50.21H
Radio hardware version: A.24.0.D4
Bootloader version: 4.5.2250.0(129185)
Chip SOC version: 2.2.5.0

PD29150 SS-BC (4K)
SPL-4.5.2250.0(129185) MNG
MicroP(LED) 0x07
TOUCH S1(v1.8,#1624)


I cant find a way to do downgrade. I've gone to this site and followed the steps but when I go to step 8, I follow that website & go to my specific device but there is no link to download the NoDo Radio file.

What can I do to downgrade my phones SPL?

seriously! a new thread? quick reply is quicker than new thread.
the AT&T NoDo Radio downloads fine for me from Rapidshare; aka the Wiki link.
unpacks fine, as well.

should have specified then.
nonetheless, will not be found. a Shipped ROM for AT&T with Radio 5.69 hasn't ever been released.
will only be 'obtained' by an AT&T update via Zune.

So does this mean that it's not possible yet?

you are just trying to downgrade?? use the NoDo build.
with XSPL installed, you can use any Radio. don't have to use AT&T Radios.

Yes I'm trying to downgrade but I read somewhere that radio file I download has to match my device and its radio version.

So then any would work from that section? How do I know which SPL I would be going in to?

brand specific. AT&T only. so, only one option, AT&T 3.03.502.04.
if you look at the Shipped ROMs page on the Wiki, it says the specifications of the ROM.
